2. RE: COMMAND data source testing failing

I have set up the same template and it works for me - no errors. I am on Zenoss 4.2.5 SUP 743.

Bear in mind that a template expects to provide performance data - ie numbers - and your test script doesn't. Different versions of Zenoss may respond differently to this scenario. For example, if there is a datapoint in your performance template then it probably will fail.
